Robotic surgery has emerged as an advanced technique for facilitating knee prosthesis implantation, especially in cases requiring high precision. However, due to the recent introduction and implementation of this approach, long-term data on its outcomes remain limited in the literature. This study aims to assess implant survival, complications and reoperation rates resulting from robotic arm-assisted partial knee arthroplasties, with a long-term follow-up period.
A retrospective analysis was conducted on 236 patients who underwent robotic arm-assisted partial knee arthroplasty, with a minimum follow-up of 10 years. Clinical outcomes were evaluated, focusing on implant survival, complications, reoperation rates, and overall patient satisfaction. The study primarily examined medial unicompartmental knee arthroplasty (UKA), with Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Knee Society Score (KSS) Part 1 and KSS Function scores assessed preoperatively and at the last follow-up.
Among the 236 patients, 212 were available at the last follow-up; satisfaction rates were overall positive, with 210 patients reporting being 'satisfied' or 'very satisfied'. Both WOMAC score and KSS showed statistically significant improvement postoperatively, both globally and in UKA patients specifically.
The study demonstrates excellent long-term satisfaction rates, improved clinical outcomes and implant survival with minimal surgical morbidity. These findings offer valuable insights into the effectiveness of robotic arm-assisted knee arthroplasty.

机器人手术已成为一种促进膝关节假体植入的先进技术，尤其是在需要高精度的情况下。然而，由于这种方法最近才被引入和应用，其长期疗效的相关数据在文献中仍然有限。本研究旨在通过长期随访评估机器人手臂辅助的部分膝关节置换术的植入物存活率、并发症和再次手术率。
对236例行机器人手臂辅助部分膝关节置换术的患者进行回顾性分析，最短随访时间为10年。评估临床疗效，重点关注植入物存活率、并发症、再次手术率和患者总体满意度。该研究主要检查内侧单髁膝关节置换术（UKA），术前及末次随访时评估西安大略和麦克马斯特大学骨关节炎指数（WOMAC）、膝关节协会评分（KSS）第1部分和KSS功能评分。
在236例患者中，末次随访时212例仍可获得随访；总体满意度较高，210例患者报告“满意”或“非常满意”。WOMAC评分和KSS评分在术后均有统计学意义的改善，无论是整体还是UKA患者。
该研究表明长期满意度极高，临床疗效改善，植入物存活率高，手术并发症极少。这些发现为机器人手臂辅助膝关节置换术的有效性提供了有价值的见解。
